Clear evidence of turned artifacts have been found from the 6th century BC: fragments of a wooden bowl in an*Etruscan*tomb in Northern Italy as well as two flat wooden dishes with decorative turned rims from*modern Turkey.[4] During the*Warring States period*in*China, c. 400 BC, the ancient Chinese used rotary lathes to sharpen tools and weapons on an industrial scale.[5] The first known painting showing a lathe dates to the 3rd century BC in*ancient Egypt.[6] The lathe was very important to the*Industrial Revolution. It is known as the*mother of machine tools, as it was the first machine tool that led to the invention of other machine tools.[7]*The first fully documented, all-metal slide rest lathe was invented by*Jacques de Vaucanson*around 1751. It was described in the*Encyclopédie. Exact drawing made with*camera obscura*of horizontal boring machine by Jan Verbruggen in Woolwich Royal Brass Foundry approx. 1778 (drawing 47 out of set of 50 drawings) In 1718 Russian engineer*Andrey Nartov*invented one of the first lathes with a mechanical cutting tool-supporting carriage and a set of gears (also known as a compound rest or slide rest) with the first to invent such a lathe probably being*Leonardo da Vinci.[8] An important early lathe in the UK was the horizontal boring machine that was installed by*Jan Verbruggen*in 1772 in the*Royal Arsenal*in*Woolwich. It was horse-powered and allowed for the production of much more accurate and stronger cannon used with success in the*American Revolutionary War*in the late 18th century. One of the key characteristics of this machine was that the workpiece was turning as opposed to the tool, making it technically a lathe.*Henry Maudslay, who later developed many improvements to the lathe, worked at the Royal Arsenal from 1783, being exposed to this machine in the Verbruggen workshop.[9]*A detailed description of Vaucanson's lathe was published decades before Maudslay perfected his version. It is likely that Maudslay was not aware of Vaucanson's work, since his first versions of the slide rest had many errors that were not present in the Vaucanson lathe. Copied from Wikipedia |

The gift (referral) that keeps on giving. The most recent machine work was counterboring some camshaft locking clamps, collected today - this modification allows the cam bearing cap bolts to be used instead of sourcing extra long M7 fasteners. Now I can change the cam belt on my daily (Alfa).
